PROTECTING-COVER FOR FUNNELS OF WAR VESSELS.

Specification of Letters Patent.

Patented Sept. 2, 1913.

Application filed Iiebruary 10, 1913. Serial No. 747,553.

To all whom it may concern:

Be it known that I, \VAUi an llnnznnnn'r, a citizen of the United States, residing at l/Veyauwega, in the county of VVaupaca and State of l/Visconsin, have invented certain new and useful Improvements in Protecting-Covers for Funnels of lVar Vessels, of which the following is a specification, ref erence being had to the accompanying drawings. i

This invention eomprehends certain new and useful improvements in protecting covers for funnels of war vessels, and has for its primary object to provide means which may be readily secured to the upper ends of the funnels and which will serve to protect the same and prevent shells, etc., from being dropped into the funnels.

An object of the invention is to provide protecting means of this character which may be securely held in position upon the end of the funnel and which may freely rotate upon the funnel, as required.

Another object is to generally improve and simplify the construction of devices of this character without materially increasing the cost of the same.

With these and other objects in view, this invention consists in certain novel details of construction, combination and arrange ment of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawings, in which- Figure 1, is an enlarged longitudinal sectional view of my invention as applied to the funnel of a vessel, said view being partly an elevation. Fig. 2, is a top plan view thereof. Fig. 3 is a reduced elevational view of the upper portion of the device. Fig. 1, is a detail view of one of the ring spacing and connecting members.

Referring more particularly to the draw ings, 1 indicates the funnel or smoke stack, and 2 the sectional ring clamped around the upper extremity of the funnel or smoke stack 1, wit-h the inwardly directed flange 3 projecting over the top of the latter to prevent downward movement of the sectional ring 2. The sections of the ring 2 are provided with the outwardly directed ears 4 at their ends with the clamping bolts 5 positioned through the ears of the sections to draw the same together, thus clamping the ring upon the funnel or smoke stack 1. It will be understood that the ears 4 are provided at both the upper and lower ends of the sections of the ring 2. The ring 2 is provided with an outwardly directed flange 6 with a flat upper face and an inclined lower face, the purpose of which will presently appear.

The lower ring 7 is clamped around the funnel or smoke stack 1 a spaced distance below the ring 2, and the ring 7 is also formed in sections, and is of the same construetion as the ring 2, with the exception of the inwardly directed flange The outwardly directed flange 8 of the ring 7 is of the same construction as the flange 6 of the ring 2 and positioned therebeneath. The sectional rings 2 and 7 are connected by means of the U-shaped connecting and spacing members 9, the main portions of which are positioned vertically, and the outwardly directed arms of the members 9 are engaged through suitable perforated cars 10 carried by the rings 2 and 7, suitable locking pins 11 being engaged through the extremities of the arms of the members 9 to prevent disengagement of the latter. A sectional hoop 12 is clamped around the funnel or smoke stack 1 immediately above the sec tional ring 7, and serves to prevent upward movement of the connected rings 7 and 2. Therefore, it will be seen that owing to the inwardly directed flange 3 and the hoop 12, longitudinal movement of the rings 7 and 2 upon the funnel or smoke stack 1 is prevented.

Positioned outwardly of the funnel or smoke stack 1 and the rings 2 and 7, is a cylindrical casing 13, which has bolted to its inner face, adjacent its lower end, the sectional ring 14 which has a long inwardly directed flange 15 provided with a flat lower face having a circular groove 16 formed therein and bearing rollers 17 mounted in said grooves and adapted for engagement with the upper flat face of the flange 8 of the ring 7. The ring 14: is also provided with a short flange 18 below the flange 15, and having an enlarged free edge for engagement below the free edge of the flange 8. Within the enlarged recess 19, at the inner edges of the flanges 15 and 18, are mounted the vertical bearing rollers 20 for engagement against the vertical edge of the flange 8, the purpose of which will be apparent. The cylindrical casing 13 also has bolted to its inner face the upper ring 21, similar to the ring 141, and also formed in sections clamped together. The upper flange adapted for engagement against the vertical edge of the flange 6. Thus it will be seen that the cylindrical casing 13 will rotate freely around the funnel or smoke stackl, j

as occasion may require.

The cylindrical casmg 13 .has an inclined flange 28 formed upon its upper edge, and

the edges of the sectional pitched roof 29 are engaged over the flanges 28 and secured j thereto by means of the bolts .30, or other.

suitable means. The sections of the pitched roof 29 are overlapped at their upper edges, 7

as shown at 31, and the bracing members 32 have their upper ends secured to the overlapped edges of the sections, by means of the angular plates 33 and bolts 34, as clearly shown in Fig. 1,. The bolts 35 secure the angular members 33 to the support 32 and the lower ends of the vertical supporting bars 32 are secured upon the flange of the ring 2, by means of the angle irons 40 and bolts 411. It will be understood that the cen- 1 tral and end horizontal supporting beams 37 extend transversely below the inclined roof members 36 forming the roof 29, and a suitable opening is provided through each end supporting beam 37 to accommodate the vertical'supporting bars 32, the supporting beams 37 having their ends bent and secured to the roof members 36, by bolts 30 and 30 or other suitable means, the bolts 30 for the central beam 37 passing through the flange 28 of the cylindrical casing 13 to secure the roof in position, as previously stated. Projecting-from one end of the roof 29 and secured to the ridge thereof, by means of the strap members 38, is a vane 39,

small cost.

While I have shown the preferred embodiment of my invention, it will be understood that minor changes may be made in the details of construction within the scope of the appended claims without departing from the spirit of the invention.

What is claimed is 1. The combination with a smoke stack, of rings clamped around the same, means for connecting said rings, flanges projecting from said rings, a cylindrical casing outwardly of said rings, rings within said icasing and having grooves formed therein, the flanges of the first mentioned rings being engaged in said grooves, bearing rollers carried by the second mentioned rings and engaged with the flanges of the first mentioned rings, and a cover for said casing.

2. The combination with a smoke stack, of rings carried thereby, connections between said rings, said rings having outwardly directed flanges, a casing around the rings, supporting means carried by the ca'sing and having recesses to accommodate the flanges of the rings carried by the smoke stack, anti-friction means positioned in the recesses, and a cover for said casing.

In testimony whereof I hereunto aflix my signature in the presence of two Witnesses.
